This book focuses on safety applications. Specifically, the author has developed and evaluated a novel protocol to improve safety on the road. The proposal combines location information of vehicles, and roadmap scenario characteristics, to improve warning message dissemination. In safety- based applications for vehicular networks author’s approaches is able to reduce the broadcast storm problem while maintaining a high message dissemination effectiveness towards surrounding vehicles. Finally, author assesses the performance of the proposed protocol using the enhanced simulation platform, evidencing the importance of an adequate simulation framework to achieve more realistic results and draw more meaningful conclusions.
